If you planning on keeping the boat over the long term I would contact Ron at Lavro. They recoat the bottoms of their boats and they may do others also. I have seen the job they do and it is great, like new. The boat I saw was over 20 years old and had been hammered on low water for years on the Mollala River in Oregon and when they were done the bottom looked great. When I saw it the boat had been used a couple more seasons (since the refinish) and the finish was holding up well.
